Depreciation Book Journal Error Message

Hello All,

Please how does one use depreciation books, what are the steps? I set up a depreciation book and I used a manual depreciation profile. But I discovered that u need to also post an acquisition using the depreciatn book journal and I keep getting this error message

“The fixed asset XXXXXXX for depreciation book XXXX does not use a depreciation method that is valid for the depreciation convention.”

Please what is missing?
